Pemba Flying Fox
The Pemba flying fox (''Pteropus voeltzkowi'') is a species of flying fox in the family Pteropodidae. It is endemic to the island of Pemba on the coast of Tanzania. Description The Pemba flying fox has a wingspan of and is one of the largest species of fruit bat. It has a fox-like face, tawny fur, orange underparts and black ears, nose and wings. The adult weight is , and the head and body length is . Distribution and habitat The Pemba flying fox occurs only on Pemba, an island about off the coast of Tanzania. Roosts occur in large trees in both primary and secondary forest, among mangroves, and in traditional graveyards. In the latter the bats are often safe and undisturbed as people seldom visit these places because of taboos. There may be up to 850 bats at a single roost. Biology Colonies of the Pemba flying fox roost during the day in large trees, emerging at dusk to forage for fruit such as figs, mangoes and breadfruit. They also eat leaves, flowers, pollen and nectar. S ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Paul Matschie
Paul Matschie Paul Matschie (11 August 1861, Brandenburg an der Havel – 7 March 1926, Friedenau) was a German zoologist. He studied mathematics and natural sciences at the Universities of Halle and Berlin, afterwards working as an unpaid volunteer at the Berlin Zoological Museum under Jean Cabanis (1816–1906). In 1892 he was in charge of the department of mammals at the museum, later becoming a curator (1895), and in 1902 attaining the title of professor. In 1924 he was appointed second director at the museum. During the years 1891–93, he described 11 new species of reptiles. A species of gecko, '' Hemidactylus matschiei'' ( Tornier, 1901), is named in his honor. Matschie organized the fifth International Congress of Zoologists in Berlin and was for some years co-editor of the journal ''Natur und Haus''. Matschie's tree-kangaroo (''Dendrolagus matschiei'') and Matschie's galago (''Galago matschiei'') are two species of mammals which bear his name. Selected writings ...

Shotgun
A shotgun (also known as a scattergun, or historically as a fowling piece) is a long gun, long-barreled firearm designed to shoot a straight-walled cartridge (firearms), cartridge known as a shotshell, which usually discharges numerous small pellets (petrology), pellet-like spherical sub-projectiles called shot (pellet), shot, or sometimes a single solid projectile called a shotgun slug, slug. Shotguns are most commonly smoothbore firearms, meaning that their gun barrels have no rifling on the inner wall, but rifled barrels for shooting slugs (slug barrels) are also available. Shotguns come in a wide variety of calibers and Gauge (firearms), gauges ranging from 5.5 mm (.22 inch) to up to , though the 12-gauge (18.53 mm or 0.729 in) and 20-gauge (15.63 mm or 0.615 in) bores are by far the most common. Almost all are breechloading, and can be single-barreled, double barreled shotgun, double-barreled, or in the form of a combination gun. Like rifles, ...

Mammals Described In 1909
Mammals () are a group of vertebrate animals constituting the class (biology), class Mammalia (), characterized by the presence of mammary glands which in Female#Mammalian female, females produce milk for feeding (nursing) their young, a neocortex (a region of the brain), fur or hair, and three ossicles, middle ear bones. These characteristics distinguish them from reptiles (including birds) from which they Genetic divergence, diverged in the Carboniferous, over 300 million years ago. Around 6,400 extant taxon, extant species of mammals have been described divided into 29 Order (biology), orders. The largest Order (biology), orders, in terms of number of species, are the rodents, bats, and Eulipotyphla (hedgehogs, Mole (animal), moles, shrews, and others).

Endemic Fauna Of Tanzania
Endemism is the state of a species being found in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can be also be referred to as an ''endemism'' or in scientific literature as an ''endemite''. For example '' Cytisus aeolicus'' is an endemite of the Italian flora. '' Adzharia renschi'' was once believed to be an endemite of the Caucasus, but it was later discovered to be a non-indigenous species from South America belonging to a different genus. The extreme opposite of an endemic species is one with a cosmopolitan distribution, having a global or widespread range. A rare alternative term for a species that is endemic is "precinctive", which applies to s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Bats Of Africa
Bats are mammals of the order Chiroptera.''cheir'', "hand" and πτερόν''pteron'', "wing". With their forelimbs adapted as wings, they are the only mammals capable of true and sustained flight. Bats are more agile in flight than most birds, flying with their very long spread-out digits covered with a thin membrane or patagium. The smallest bat, and arguably the smallest extant mammal, is Kitti's hog-nosed bat, which is in length, across the wings and in mass. The largest bats are the flying foxes, with the giant golden-crowned flying fox, ''Acerodon jubatus'', reaching a weight of and having a wingspan of . The second largest order of mammals after rodents, bats comprise about 20% of all classified mammal species worldwide, with over 1,400 species. These were traditionally divided into two suborders: the largely fruit-eating megabats, and the echolocating microbats. But more recent evidence has supported dividing the order into Yinpterochiroptera and Yangochirop ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pteropus
''Pteropus'' (suborder Yinpterochiroptera) is a genus of megabats which are among the largest bats in the world. They are commonly known as fruit bats or flying foxes, among other colloquial names. They live in South Asia, Southeast Asia, Australia, East Africa, and some oceanic islands in the Indian and Pacific Oceans. There are at least 60 Extant taxon, extant species in the genus. Flying foxes eat fruit and other plant matter, and occasionally consume insects as well. They locate resources with their keen sense of smell. Most, but not all, are nocturnality, nocturnal. They navigate with keen eyesight, as they cannot Animal echolocation, echolocate. They have R/K selection theory#K-selection, long life spans and low reproductive outputs, with females of most species producing only one offspring per year. Their slow life history makes their populations vulnerable to threats such as Overexploitation, overhunting, culling, and natural disasters. Six flying fox species have been ...

Ecotourism
Ecotourism is a form of tourism involving responsible travel (using sustainable transport) to natural areas, conserving the environment, and improving the well-being of the local people. Its purpose may be to educate the traveler, to provide funds for ecological conservation, to directly benefit the economic development and political empowerment of local communities, or to foster respect for different cultures and for human rights. Since the 1980s, ecotourism has been considered a critical endeavor by environmentalists, so that future generations may experience destinations relatively untouched by human intervention. Ecotourism may focus on educating travelers on local environments and natural surroundings with an eye to ecological conservation. Some include in the definition of ecotourism the effort to produce economic opportunities that make conservation of natural resources financially possible. Generally, ecotourism deals with interaction with biotic components of the natura ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vulnerable Species
A vulnerable species is a species which has been Conservation status, categorized by the International Union for Conservation of Nature as being threatened species, threatened with extinction unless the circumstances that are threatened species, threatening its survival and reproduction improve. Vulnerability is mainly caused by habitat loss or destruction of the species' home. Vulnerable habitat or species are monitored and can become increasingly threatened. Some species listed as "vulnerable" may be common in captivity (animal), captivity, an example being the military macaw. There are currently 5196 animals and 6789 plants classified as Vulnerable, compared with 1998 levels of 2815 and 3222, respectively. Practices such as cryoconservation of animal genetic resources have been enforced in efforts to conserve vulnerable breeds of livestock specifically. Criteria The International Union for Conservation of Nature uses several criteria to enter species in this category. A tax ...

Taboo
A taboo or tabu is a social group's ban, prohibition, or avoidance of something (usually an utterance or behavior) based on the group's sense that it is excessively repulsive, sacred, or allowed only for certain persons.''Encyclopædia Britannica Online''.Taboo. Encyclopædia Britannica Inc., 2012. Retrieved 21 Mar. 2012 Such prohibitions are present in virtually all societies. Taboos may be prohibited explicitly, for example within a legal system or religion, or implicitly, for example by social norms or conventions followed by a particular culture or organization. Taboos are often meant to protect the individual, but there are other reasons for their development. An ecological or medical background is apparent in many, including some that are seen as religious or spiritual in origin. Taboos can help use a resource more efficiently, but when applied to only a subsection of the community they can also serve to suppress said subsection of the community. A taboo acknowledged by a ...
